Onshore wind[ edit ] Wind power harnesses mechanical energy from the constant flow of air over the surface of the earth. Wind power stations generally consist of wind farmsfields of wind turbines in locations with relatively high winds. A primary publicity issue regarding wind turbines are their older predecessors, such as the Altamont Pass Wind Farm in California.
Sadly enough, the same researches shows that there has been an increase in the rate of usage of fossil fuel and their use is expected to continue increasing steadily. Just as an example from the many problems the world faces today, the dilemma faced in the world is that China, in her quest to become industrialized and modern, is continuously building power plants which are coal-fired, a factor that has led to continuous emission of Carbon dioxide into the atmosphere.
Since fossil fuels are mainly composed of carbon, they always release this carbon they are composed of in the form of CO2when they are burned inform of gasoline or in a coal fired plant Ou et al. The most common fossil fuels used in the world today are oil, natural gas and coal.
Liquefied petroleum gas LPG is another form of fossil fuel which is mainly derived from natural gas production. Pulverized coal is always blown into the furnace as coal is burned in power plants Casper, Water flowing through the tubes found in this furnace is always heated under pressure to boiling point; they blast through a turbine turning a generator to produce electricity.
As coal is being burned, greenhouse gases such as Carbon dioxide, nitrogen oxide and sulphur dioxide are emitted into the atmosphere. Sulphur particles are partially removed by filters and scrubbers and while close to 90 percent of emission of sulphur are usually caught, the remaining 10 percent always find their ways into the atmosphere.
By virtue of its high content of carbon, Coal emits the highest amount of carbon dioxide compared to other fossil fuels. It makes the biggest source of fuel used to produce electricity worldwide National Science Foundation U.
Coal combustion is the main contributor of greenhouse gas effect globally. In addition to CO2, methane is another by-product of coal with more side effect on the environment than CO2 since it has global warming potential GWP 25 times higher than that of CO2 when compared over a lifespan of more than years.
With regards to the survey conducted by the Union of Concerned Scientists UCSone of the largest coal plants is megawatt and it produces 3. This is approximated to be able to provide power to a city ofThe plant burns 1, tons of coal, uses00 tons of limestone and 2.
This plant releases into the atmosphere of the earth the following: And lastly are the small particulates that are hazardous to health causing damage of the lung. When fossil fuels are not completely burnt, their hydrocarbon elements are released into the environment causing smog.
Improperly burned carbon is also released into the atmosphere in the form of Carbon monoxide which is both poisonous and also contributes to global warming Casper, Ash from these fuels commonly known as sludge consist of many pollutants including heavy metals like mercury and lead, arsenic, uranium and cadmium.
Furthermore, these heavy metals accumulate along the food chain causing major human health problems like cancer.The Sources and Solutions: Fossil Fuels Cars and trucks release nitrogen into the atmosphere, which contributes to nutrient pollution in our air and water. Airborne nitrogen pollution affects not only the quality of the air we breathe, but also the land and the water.
Jun 10, · THE IMPACT OF FOSSIL FUELS ON THE ENVIRONMENT.
by (Name) The Name of the Class (Course) The overall environmental impact of fossil fuel includes acid rain, oil spills, air quality deterioration and global warming.
Impact of Fossil Fuels on the Environment Global Warming. The environmental effects of using fossil fuels can have a serious impact on the quality of life. The process of burning fossil fuels combines carbon in the fuel with oxygen in the air to form carbon dioxide (CO 2) that is released to the srmvision.com is true for all fossil fuels and more so with coal and oil.
Of the many environmental and public health risks associated with burning fossil fuels, the most serious in terms of its universal and potentially irreversible consequences is global warming. In , approximately 78 percent of US global warming emissions were energy-related emissions of carbon dioxide.
The primary reason that fossil fuels are harmful to the environment is that their use produces large amounts of greenhouse gases. These gases cause heat to build up in the atmosphere and raise the average temperature of the planet.
Fossil fuels also pollute the air when they're burned and may cause. The environmental impact of wind power when compared to the environmental impacts of fossil fuels, is relatively minor. According to the IPCC, in assessments of the life-cycle global warming potential of energy sources, wind turbines have a median value of between 12 and 11 (g CO 2 eq / kWh) depending, respectively, on if offshore or.
